kilo openstack-dashboard fails to install due to missing packages on ubuntu 14.04

I'm using Ubuntu Cloud Archive for OpenStack Kilo

Steps how to reproduce this on a fresh Ubuntu 14.04 instance:

sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install software-properties-common
sudo add-apt-repository cloud-archive:kilo
sudo apt-get install python-django-horizon

I think this is a problem with the package archives for 14.04 rather than, horizon.

It looks like this was fixed in vivid: https://launchpad.net/ubuntu/+source/horizon/1:2015.1~b3-0ubuntu2

If I install the ubuntu2 version of the packages, or just the existing ones with --force-depends I end up with this common django/simplejson problem:

The packages are in trusty-updates now, but the simplejson issue remains. See: https://bugs.launchpad.net/ubuntu/+source/horizon/+bug/1443787

Confirming that latest trusty-updates including python-compressor_1.4-2ubuntu3~cloud0_all.deb fixed this for me

Hmm - looks like there is a still a problem - one of the xstatic deps is not being ignored correctly.

This bug was fixed in the package horizon - 1:2015.1~rc1-0ubuntu2

---------------
horizon (1:2015.1~rc1-0ubuntu2) vivid; urgency=medium

  * d/pydist-overrides: Amend typo xstatic-angular-irdragndrop ->
    xstatic-angular-lrdragndrop to ensure that embedded xstatic deps are
    correctly ignored when generating dependencies (LP: #1439837).
